448 grams is nothing to get excited about. It is not a bad weight for a modern crankset but many of us are currently riding lighter cranksets so not sure why there would be any excitement. They seem kind of expensive for the weight.

What other cranks are available at or below 450g for crank, BB, and spider at or below $1100? Thats a serious question BTW, as I'm not really up on WW cranks.

The THM Clavicula crank is 336 grams and a THM shell with bearings is 74 grams, total 410 grams. The Ax Lightness is about the same.

It is not clear so far if the Ciamillo 448 grams (or 454) includes a BB and/or what kind of BB, but even if it does it is not breaking any new ground and sells for about what you can pay for a Clavicula or Ax Lightness crank and is heavier. But if you really like the looks and don’t mind the extra weight then it looks like a nice crankset.

I like it Colour options on the anodised part? Blue doesn't do it for me lol. That spider looks a little over engineered, plenty of meat could be removed from that me thinks? I'm assuming this has a Hirth joint yeah? Like Specalized, Campagnolo and my dearly departed Sweet Wings?

Impressive, Mr. Ciamillo, but not enough to get me warmed up to wanting one. Q-factor is once again too wide for my liking and I won't even mention how little ankle clearance it offers us duck-footed cyclists (which I am to a mild degree). They don't look half bad though. May these cranks come to the market and beget many happy costumers!

Regarding the orientation of the spider.. the spider is removable and uses the same spline as the arm. The spider was simply placed on the spline for the photograph in the wrong orientation.

Regarding the weight, it will come down .. significantly I think; but I am more concerned about stiffness and robustness than weight at this point. The crank is one of the largest losses of power transfer. Testing is going well and weight will come off but I am not concerned about the Vuma weight that much because I don't know if the push to achieve that weight ultimately resulted in its being discontinued.

Regarding the Q and chainline.. On BB30 frames, there is a large spacer on the non-drive side so to reduce Q I just need the customer to verify that with their existing setup, a reduction in Q would not cause a clearance issue with chainstay and I am happy to shorten the non-drive spindle and spacer. This will not affect the 43.5 chainline for the drive side at all.

I know we are about weight here and pushing the envelope is what I am all about but on this project robustness and stiffness are my first priorities. I love working with carbon and enjoy applying the products and processing advice given to me by the folks at TCR Composites.. I will share some of the manufacturing process on this project shortly.

Thank you for all the compliments on the design. I will post some pics on a bike soon.
